Description

This embodiment relates to a cart for transportation.

2. Description of the Related Art Conventionally, for example, in stores, factories, and the like, carts for transporting loads such as food have been used. Such a carriage for transportation has a carriage body having a pair of side frames, and the carriage body has a heat-insulating carriage cover in order to insulate or protect a load such as food from heat or cold. be worn. As such a cart for transportation, for example, the one disclosed in Patent Document 1 is known.

However, conventional carriage covers for carriages for transportation are made of, for example, sewn sheet materials, and are generally thin and flexible (see Patent Document 1, for example). For this reason, the conventional trolley cover has a problem that it is difficult to sufficiently improve the heat insulation performance and to sufficiently protect the load inside.

On the other hand, it is also conceivable to assemble the panels into a box shape and mount them on the trolley body. It is structurally difficult to provide an intermediate shelf inside the box-like panel container when it is desired to mount it. This is because containers made of such panels in the shape of a box are often required to be lightweight and moderately heat-insulating. materials are often used. For this reason, it is technically possible to attach an intermediate shelf by, for example, attaching a lightweight shelf made of the same material as the panel to the inner side surface of the container using a simple method such as hook-and-loop fasteners. This is because they do not have the durability to support heavy objects. If a heavy object is placed on the panel, the panel may bend, the hook-and-loop fastener attached to the side panel may peel off, or the side panel itself may be damaged or deformed.

FIG. 3 is a perspective view of the carriage body 50. As shown in FIG.

As shown in FIGS. 1 to 3, the carriage 10 for transportation according to the first embodiment includes a carriage body 50 and a panel container 30 mounted on the upper side of the floor surface of the carriage body 50. As shown in FIGS. The panel container 30 is mounted on the carriage body 50, but when the panel container 30 is not used, the panel container 30 can be unloaded from the carriage body 50 together. The panel container 30 may be simply placed on the carriage body 50. In order to prevent the panel container 30 from slipping down from the carriage body 50 due to vibration or the like during transportation of the transportation carriage 10, a detachable attachment such as a hook-and-loop fastener is provided. The panel container 30 and the carriage body 50 may be engaged by an engaging means. Moreover, the panel container 30 may be non-removably fixed to the carriage body 50 .

The transport trolley 10 is used, for example, in stores, factories, physical distribution processes, etc., when storing or transporting loads that need to be kept cool or warm. In such a carriage 10 for transportation, a storage space 20 capable of storing a load is surrounded by the six panels 11 to 16 constituting the panel container 30 to form an insulating space. It is configured such that the temperature change inside the truck 10 is suppressed as much as possible. On the other hand, when the carriage 10 for transportation is not used, for example, after removing the panel container 30 from the carriage body 50, it is nested with the carriage body 50 of the other same carriage 10 for transportation, or the carriage body 50 itself is folded. Thereby, it is possible to compactly store the carriage bodies 50 of the plurality of carriages 10 for transportation.

In the present disclosure, for convenience of explanation, a so-called six-wheeled cart or six-wheeled truck having a pair of side frames, a connecting member, and six wheels is illustrated as the truck body of the truck for transportation. However, the trolley for transportation of the present disclosure is not limited to this, and any trolley that has a space for mounting a panel container, for example, a cart with four wheels, a general hand-push type trolley, or a pair of left and right It is also applicable to a so-called basket trolley having a frame on the back side in addition to the side frame, or a roll box pallet defined by JIS Z0610 or the like.

Inside the panel container 30 of the carriage 10 for transportation, a shelf plate 91 extending in the horizontal direction is arranged at a substantially intermediate height in the vertical direction to partition the storage space 20 vertically. Both ends of the shelf 91 are held by a pair of ladder-shaped shelf holders 81 extending vertically inside the panel container 30 . The shelf plate holder 81 is fixed by pressing its upper and lower ends against the panel container 30, the details of which will be described later. Thereby, in the inside of the panel container 30, apart from the load N2 mounted on the floor side, the load N1 can be loaded on the shelf plate 91 which is vertically separated from the load N2.

Further, inside the panel container 30, a heat storage material storage section 70 is provided along the inner surface of the panel. The heat storage material storage unit 70 contains a heat storage material cooled or heated to a predetermined temperature, and has a function of cooling or heating the air in the storage space 20 to a predetermined temperature. The heat storage material storage part 70 may have a structure in which the lid can be closed with a chuck or hook-and-loop fastener so that the stored heat storage material does not fall. In addition, in order to facilitate transmission of cold air and heat from the heat storage material to the storage space 20, the heat storage material storage part 70 may be formed of fabric, non-woven fabric, mesh structural material, wire mesh structural material, etc. with many gaps. good.

Next, based on FIG. 3, the structure of the trolley main body 50 will be described. The bogie body 50 includes a first side frame 51, a second side frame 52, and a connecting member 53 that connects the first side frame 51 and the second side frame 52 to each other. The connecting member 53 has six wheels 61 to 66, and the wheels 61 to 66 are attached to the connecting member 53 so as to face downward.

The first side frame is formed in a ladder shape and has a pair of struts 55 and a plurality of horizontal beams 56 each extending in the X direction between the pair of struts 55 . The plurality of horizontal beams 56 are arranged at substantially equal intervals from each other along the vertical direction. Two wheels 61 and 62 are provided on the lower side of the first side frame 51 .

A pair of struts 55 are directly connected to the wheel mounting frame 67 . Of the pair of pillars 55, the pillar 55 on the +X direction side is directly connected to the wheel mounting frame 67, and the other pillar 55 on the -X direction side is not directly connected to the wheel mounting frame 67, and is separated from the wheel mounting frame 67. It is good also as a structure to carry out. By doing so, it is possible to prevent the central frame 57 of the other carrier 10 from interfering with the support 55 during nesting.

The second side frame 52 is provided at the other end in the +Y direction of the carriage body 50 in the longitudinal direction, and protrudes upward from the connecting member 53 . The configuration of the second side frame 52 is substantially the same as the configuration of the first side frame 51 , and two wheels 65 and 66 are provided on the lower side of the second side frame 52 . Of the pair of pillars 55, the pillar 55 on the -X direction side is directly connected to the wheel mounting frame 67, and the other pillar 55 on the +X direction side is not directly connected to the wheel mounting frame 67 and is separated from the wheel mounting frame 67. As a structure to do so, the second side frame 52 may be arranged so as to be point-symmetrical to the first side frame 51 in a plan view. By doing so, nesting can be efficiently performed without worrying about the orientation of the carriage body 50 .

The connecting member 53 has a central frame 57 extending in the Y direction, which is the longitudinal direction of the bogie body 50, and three wheel mounting frames 67 to 69 respectively connected to the central frame 57 and extending in the X direction. The wheel mounting frames 67 to 69 are arranged below the central frame 57 so as to be separated from each other. The center frame 57 is arranged substantially in the center of the carriage body 50 in the Y direction.

The wheel mounting frames 67 to 69 include a first wheel mounting frame 67 arranged on the side of the first side frame 51 and a second wheel mounting frame 68 arranged between the first side frame 51 and the second side frame 52. and a third wheel mounting frame 69 arranged on the second side frame 52 side.

The distance in the Y direction between the first wheel mounting frame 67 and the second wheel mounting frame 68 and the distance in the Y direction between the second wheel mounting frame 68 and the third wheel mounting frame 69 may be the same. can be different.

The first wheel mounting frame 67 is provided at the -Y direction end of the central frame 57, and the +X direction end and the -X direction end of the first wheel mounting frame 67 are provided with the first wheel 61 and the -X direction end, respectively. A second wheel 62 is attached. Similarly, the second wheel mounting frame 68 is provided substantially in the center of the central frame 57 in the Y direction, and the +X direction side end and the -X direction side end of the second wheel mounting frame 68 are respectively provided with third wheels. A wheel 63 and a fourth wheel 64 are attached. The third wheel mounting frame 69 is provided at the +Y direction side end of the central frame 57, and the +X direction side end and the -X direction side end of the third wheel mounting frame 69 are respectively provided with the fifth wheels 65. and a sixth wheel 66 are attached.

The wheels 61-66 are composed of the first wheel 61, the second wheel 62, the third wheel 63, the fourth wheel 64, the fifth wheel 65 and the sixth wheel 66, as described above. Among them, the first wheel 61, the second wheel 62, the fifth wheel 65, and the sixth wheel 66 are free wheels, and each rotates along an axle parallel to the horizontal plane (XY plane), and rotates in the vertical direction. It is possible to swivel about an axis (Z-axis). On the other hand, the third wheel 63 and the fourth wheel 64 are fixed wheels, and although they can rotate along axes parallel to the horizontal plane (XY plane), they can rotate around the vertical axis (Z axis). It is impossible to turn.

note that. The wheels 61 to 66 are connected to the center fixed wheel (the third wheel 63 and the fourth wheel 64) and either the front or rear wheel so that the transport truck 10 can travel straight ahead with stability when the load is placed on it. Two wheels, one free wheel (the first wheel 61 and the second wheel 62, or the fifth wheel 65 and the sixth wheel 66) may be combined to be grounded.

When no load is placed on the transport cart 10, the central fixed wheels (the third wheel 63 and the fourth wheel 64) are grounded in order to facilitate turning and nesting, and to facilitate turning in a small radius. Instead, only the front and rear swivel wheels (the first wheel 61, the second wheel 62, the fifth wheel 65 and the sixth wheel 66) may be grounded. In this case, either the first wheel 61 and the second wheel 62 or the fifth wheel 65 and the sixth wheel 66, either front or rear wheels, are switched from free wheels to fixed wheels in order to ensure running aptitude. can have a structure. However, not limited to this, the trolley body 50 has four wheels 61, 62, 65, and 66, and does not have the second wheel mounting frame 68, the third wheel 63, and the fourth wheel 64. good too.

A foldable bottom plate 58 is provided on the upper side of the connecting member 53 . The bottom plate 58 has a substantially rectangular parallelepiped shape and is arranged to extend between the first side frame 51 and the second side frame 52 along the Y direction, and is substantially separated from the first side frame 51 and the second side frame 52 in the X direction. have the same length. The bottom plate 58 has sufficient strength to hold the load of the load of the cart 10 for transportation. In addition, the bottom plate 58 is not necessarily required for the carriage 10 for transportation.

The bottom plate 58 is rotatable about the rotation axis in the X direction with respect to the connecting member 53. Although not shown, the assembled state arranged above the connecting member 53 and the +Y direction side end of the bottom plate 58 are not shown. It can be lifted relative to the connecting member 53 with the vicinity thereof as a rotation axis and folded to a position adjacent to the second side frame 52 . That is, when the panel container 30 is mounted on the carriage 10 for transportation, the bottom plate 58 is arranged in a horizontal plane, and when the panel container 30 is removed from the carriage main body 50, the bottom plate 58 rotates upward and moves upward. It is arranged at a position adjacent to the second side frame 52 .

(b) Configuration of Panel Container The configuration of the panel container 30 and the panels 11 to 16 will be described with reference to FIGS. 1 to 3. FIG.

The panel container 30 in this embodiment is constructed by assembling the panels 11 to 16 into a substantially rectangular parallelepiped shape that forms a heat-insulating space inside, and the adjacent portions of the panels ensure the airtightness of the panel container. Therefore, it is fixed by an adhesive or the like, and cannot be disassembled into individual panels. However, only the front panel 12 can be opened and closed for the convenience of putting articles in and out of the panel container 30 . FIG. 1 shows a carriage 10 for transportation in which a panel container 30 is mounted on a carriage body 50 and the front panel 12 is open, and FIG. This is the carriage 10 for transportation in which the accommodation space 20 is a heat insulating space.

As shown in FIG. 1, the panels 11 to 16 of the panel container 30 form a substantially rectangular parallelepiped shape except for the open front panel 12, and include the top panel 11, the front panel 12, the rear panel 13, the left panel 14, and the right panel. It includes panel 15 and bottom panel 16 . The top panel 11, the front panel 12, the rear panel 13, the left panel 14, the right panel 15 and the bottom panel 16 each have a substantially rectangular main surface. The main surfaces of the front panel 12 and the rear panel 13 have substantially the same size, and the main surfaces of the left panel 14 and the right panel 15 have substantially the same size. is doing. Each of the panels 11 to 16 is composed of a plate-like member having rigidity and is flexibly not deformed during use.

When the panel container 30 is assembled, the six panels 11 to 16 surround the storage space 20 for storing the load, thereby forming a heat insulating space in the storage space 20. The end surfaces of the six panels 11-16 are in close contact with the main surface or end surface of any other panel 11-16, thereby ensuring the sealing of the housing space 20. As shown in FIG. When the heat-insulating space is surrounded by a heat-insulating material, the inflow and outflow of heat to and from the outside is restricted, and good heat-insulating properties can be maintained.

When cargo that requires temperature control is loaded on the carriage 10 for transportation and is not used, the panel container 30 can be separated from the carriage body 50 and stored, and the carriage bodies 50 can be partially folded or It becomes possible to nest with other carts 10 for transportation.

(c) Internal Structure of Panel The structure of the panels 11 to 16 will be described. 4 is a cross-sectional view showing the heat insulation portion 40 of each of the panels 11 to 16, and FIGS.

As shown in FIG. 4, the heat insulating portion 40 of each panel 11 to 16 has a vacuum heat insulating material 41, a foam heat insulating material 42, a heat insulating surrounding portion 43, a heat insulating material protection member 44, and a heat shielding sheet 45. As shown in FIG.

The vacuum heat insulating material 41 is attached to the foam heat insulating material 42 . The vacuum heat insulating material 41 is composed of a core material 41a and an exterior material 41b provided around the core material 41a. A foamed heat insulating material 42 is arranged on the housing space 20 side (lower side in FIG. 4) of the vacuum heat insulating material 41 . As a result, when the load stored in the storage space 20 collides with the panels 11 to 16, the foamed heat insulating material 42 absorbs the impact, thereby reducing the risk of the vacuum heat insulating material 41 being damaged. be able to.

The foam insulation 42 can be arranged adjacent to the vacuum insulation 41 at least on the housing space 20 side, and can be made of, for example, polyurethane foam, polystyrene foam, or both.

The heat insulating enclosing part 43 is arranged so as to surround the vacuum heat insulating material 41 . The heat insulating surrounding portion 43 is arranged adjacent to a portion of the foam heat insulating material 42 and fixed to the foam heat insulating material 42 . By arranging the heat insulating enclosing part 43 so as to surround the vacuum heat insulating material 41, the heat insulating performance is improved as compared with the case where the heat insulating enclosing part 43 is not arranged. Alternatively, the vacuum heat insulating material 41 may have substantially the same cross-sectional area as the foam heat insulating material 42, and a panel configuration may be adopted in which the heat insulating enclosing portion 43 is not used.

The heat insulating material protection member 44 is provided so as to be partially adjacent to the heat insulating enclosing part 43 and mainly serves to protect the vacuum heat insulating material 41 . As the heat insulator protection member 44, for example, an organic polymer protection material can be used.

The heat shield sheet 45 is formed so as to cover the entire outer peripheries of the vacuum heat insulating material 41 , the foam heat insulating material 42 , the heat insulating surrounding portion 43 and the heat insulating material protection member 44 . The heat shield sheet 45 can be arranged so as to cover the entirety of the vacuum heat insulating material 41 and the foam heat insulating material 42 . Examples of the heat shield sheet 45 include a multi-layer sheet containing metal foil, and a vapor deposition sheet in which a vapor deposition layer is formed on one side of a resin sheet.

As shown in FIG. 5A, the vacuum heat insulating material 41 is composed of a core material 41a and an exterior material 41b having a gas barrier property, and is a heat insulating material obtained by decompressing the interior of the exterior material 41b. . FIG. 5(b) is another example of the vacuum heat insulating material 41. As shown in FIG. In FIG. 5(a), voids are formed at both ends inside the vacuum heat insulating material 41, but in FIG. 5(b), no voids are formed. Voids may or may not occur depending on the method of manufacturing the vacuum heat insulating material 41 .

For the core material 41a, a material used for the core material of a conventionally known vacuum insulation material can be used. For example, powder such as silica, foam such as urethane polymer, fiber such as glass wool, etc. Porous bodies may also be used.

The exterior material 41b is a member that covers the outer periphery of the core material 41a, and may be a flexible sheet in which a thermal adhesive layer and a gas barrier layer are laminated in this order from the core material 41a. As the gas barrier layer, a metal foil, a vapor deposition sheet in which a vapor deposition layer is formed on one side of a resin sheet, or the like may be used. A metal foil, for example aluminum, can be used. For the deposited layer, for example, aluminum, aluminum oxide, silicon oxide can be used.

Like the left panel 14, the right panel 15 is also arranged below the top panel 11 and above the bottom panel 16, with the main surface of the right panel 15 substantially parallel to the Z direction. It is Like the left panel 14, the right panel 15 is composed of a single plate-like member. In common with the left panel 14 , the right panel 15 may be detachably engaged with the second side frame 52 or fixed in a non-detachable manner. The right panel 15 is unfoldably connected to the top panel, the bottom panel 16, and the rear panel 13 adjacent to the front panel 12, and ensures the airtightness of the storage space 20 when the front panel 12 is closed. ing. One of the left panel 14 and the right panel 15 can be called a first side panel, and the other can be called a second side panel.

(v) Top Panel As shown in FIG. 1, the top panel 11 is a panel arranged above the front panel 12, the rear panel 13, the left panel 14 and the right panel 15 in the panel container 30. , the main surface of the top panel 11 is arranged in a direction substantially parallel to the horizontal plane. The top panel 11 is unfoldably connected to the adjacent left panel 14, right panel 15 and bottom panel 16 except for the front panel 12, ensuring the airtightness of the storage space 20 when the front panel 12 is closed. is doing.

(vi) Bottom Panel The bottom panel 16 is a panel arranged below the front panel 12 , the rear panel 13 , the left panel 14 and the right panel 15 . The bottom panel 16 is disposed above the bottom plate 58 of the carriage body 50 and between the first side frame 51 and the second side frame 52 with the main surface of the bottom panel 16 oriented substantially parallel to the horizontal plane. ing.

The airtightness of the storage space 20 is ensured. In addition, since the bottom panel 16 is more susceptible to load than other panels due to direct contact or pressure contact with cargo and shelf plate holders 81, a reinforcing plate having appropriate strength is laid on the bottom panel 16. may This includes, for example, plastic corrugated cardboard.

(e) Configuration of Shelf Board and Shelf Board Holder As shown in FIG. 1, the shelf board holder 81 is composed of a pair of holder struts 101 extending in the vertical direction and horizontal beams 102 connecting them in the X direction. One of the ladder-like structures 109 is arranged close to the inner surface of the left panel 14 on the -Y direction side in FIG. 1, and the other is not shown. It is located close to the inner surface of the right panel 15 . These two sets of ladder-like structures 109 can also be referred to as the first shelf retainer and the second shelf retainer, respectively. Further, the shelf plate 91 preferably has a rigid plate-like structure such as a metal plate or a resin plate, but may have a mesh structure in which metal wires or resin wires are woven, for example, and both ends have a ladder-like structure. It may be constructed from a flexible material such as fabric if it can engage the body 109 .

Details of the configurations of the shelf plate holder 81 and the shelf plate 91 will be described with reference to FIGS. 6 and 7. FIG. 6A and 6B are a side view and a front view showing the arrangement of shelf plate holders 81 inside the panel container 30. FIG. FIG. 6A is a cross-sectional view of the panel container 30 cut along a plane perpendicular to the Y-axis near the center in the Y-direction, viewed from the +Y-direction side. FIG. 6B is a front view of the panel container 30 viewed from the +X direction side with the front panel 12 removed. FIG. 7 is an enlarged view of the portion A, which is the contact portion between the ladder-like structure 109 and the shelf plate 91 in FIG. 6(b).

As shown in FIGS. 6(a) and 6(b), the shelf plate holder 81 has two sets of ladder-like structures 109 of the same structure at positions close to the left panel 14 side and the right panel 15 side, respectively. It is fixed in contact with the top panel 11 and the bottom panel 16 of the panel container 30 while extending in the vertical direction. The two sets of ladder-like structures 109 may not have the same structure, but if they have the same structure, they are symmetrical even if they are arranged in opposite directions. Defects are less likely to occur, which is advantageous in terms of operation and mass production.

As shown in FIG. 6(a), the ladder-like structure 109 includes a pair of holder supports 101 extending in the vertical direction, and fixing plates 104 having wide areas at the upper and lower ends of each. . This is done by increasing the contact area of the portion where the holder strut 101 abuts on the top panel 11 and bottom panel 16 as much as possible, thereby avoiding the application of a local concentrated load to the top panel 11 and bottom panel 16. , to suppress deformation and damage to the panel.

In this embodiment, the fixed plate 104 has a square planar shape, but the planar shape can be any shape such as a rectangle, a circle, or a triangle as long as the contact area with the panel can be increased. In addition, the main surface of the fixing plate 104 that contacts the panel is arranged so as to be substantially perpendicular to the axis of the support column 101, but it can be tilted at a small angle with respect to the plane perpendicular to the axis. It has a structure that allows By doing so, even when the axis of the holder support 101 and the panel surfaces of the top panel 11 and the bottom panel 16 are not strictly perpendicular to each other, the inclination of the fixing plate 104 causes the main surface of the fixing plate 104 to move. can be in contact with the main surface of the panel substantially in parallel, and application of a concentrated load to the panel can be suppressed as much as possible.

Further, an adjuster 103 is provided between the upper end of the holder post 101 of the ladder-like structure 109 and the fixing plate 104 . The adjuster 103 has a function of adjusting the height from the fixing plate 104 at the lower end of the support column 101 to the fixing plate 104 at the upper end. By having a structure corresponding to a nut, the height of the ladder-like structure 109 can be extended or shortened by rotating one relative to the other. With such a structure, even when the height of the inside of the panel container 30 is different, the height of the ladder-like structure 109 can be arbitrarily adjusted so that the shelf board holder 81 can be positioned relative to the panel container 30. An appropriate compressive load can be applied to the top panel 11 and the bottom panel 16 so that they can be stably fixed.

However, the structure of the adjuster 103 that adjusts the height of the ladder-like structure 109 is not limited to the above, and may be a mechanism that adjusts the height by pneumatic pressure or hydraulic pressure. Further, a method of adding or removing a required number of fragmentary additional members for increasing or decreasing the height of the holder strut 101 in the axial direction by a screw method or a fitting connection method may be employed.

A pair of holder struts 101 of the ladder-like structure 109 are horizontally connected to each other by a plurality of horizontal beams 102 . The horizontal beams 102 connect the holding fixture posts 101 to each other to improve strength. It plays a role of stably supporting the plate 91 . In this embodiment, the horizontal beams 102 are arranged at regular intervals in the vertical direction, but the vertical intervals need not be the same. Also, the number of horizontal beams can be appropriately determined in consideration of the assumed installation position and number of installed shelf boards. In the present embodiment, the holder struts 101 and the horizontal beams 102 are constructed of a pipe-shaped structure having a circular cross section. It may be of any other cross-sectional shape.

The structure of the portion where the ladder-like structure 109 supports the shelf board 91 is shown in FIGS. 7(a) and 7(b). As shown in FIG. 7A, a shelf board hook 105 perpendicular to the main surface of the shelf board 91 is attached to the tip of the shelf board 91 in the -Y direction, and the tip of the shelf board hook 105 is further It has a hook-like bent structure. This shelf board hook 105 is also attached to the opposite end of the shelf board 91 . The main body of the shelf board 91 is placed on the horizontal rails 102 of the ladder-like structure 109, and the shelf board hook 105 at the tip is arranged so as to surround the horizontal rails 102. Even when it is about to shift along the direction, the shelf board hook 105 is hooked on the horizontal beam 102 and plays a role as a stopper, so that the shelf board 91 is prevented from falling off the ladder-like structure 109 carelessly. be able to.

Moreover, when such shelf board hooks 105 are attached, as shown in FIG. That is, it can be held by being hooked on the horizontal beam 102 at an angle of 90 degrees, and the risk of losing the shelf when not in use can be reduced. However, the tip structure of the shelf board 91 may not have such shelf board hooks 105, and may have shelf board hooks of different arrangement and shape or other fixing means as in the modified examples described later. may be For example, it may be fixed detachably with a surface fastener for simplicity. In this case, since the load of the luggage is supported by the horizontal beams 102 of the ladder-like structure 109, it is not necessary to give the hook-and-loop fastener itself a strong engaging force.

Thus, in the carriage 10 for transportation according to the first embodiment, the left panel 14 is positioned between the first side frame 51 and the front panel 12, which are a pair of side frames of the carriage body 50. A panel container 30 is arranged such that the right panel 15 is arranged between the panel 12 and the panel container 30 . Inside the panel container 30, ladder-like structures 109, which are two sets of shelf board holders separated from each other and which constitute the shelf board holder 81, are provided near the left panel 14 and near the right panel 15, respectively. It extends from the bottom panel 16 to the top panel 11 and is detachably fixed to the panel container 30 by pressing the front end portion against both panels. Further, a shelf board 91 is horizontally extended and supported by a shelf board holder 81 so as to straddle the horizontal beams 102 of the ladder-like structure 109 as two sets of shelf board holders.

As described above, even when the storage space 20 inside the panel container 30 does not have a space for directly placing luggage on the floor surface, that is, the bottom panel 16, the storage space 20 can be stored on the shelf plate 91 provided at the middle position in the height direction. In addition, additional luggage can be loaded, which increases luggage storage efficiency. This is particularly effective when the load is not rectangular parallelepiped, or when the load itself is soft and easily deformed. In addition, when storing cargo that is to be stored at a lower temperature than other cargo, it is more advantageous to store the cargo higher because the cold air of the heat storage material flows downward from above. By providing the shelf plate 91 inside the container 30 , it is possible to easily store specific cargo at a higher position inside the panel container 30 .

In addition, the shelf board 91 is not engaged with the side panel by a weak engaging means such as a hook-and-loop fastener, but two sets of ladder-like structures 109 that are pressed against both the top panel 11 and the bottom panel 16. Since it is supported by the shelf plate holder 81 composed of , a heavier load can be loaded on the shelf plate. Further, in the shelf board holder 81, the plurality of horizontal beams 102 directly supporting the shelf board 91 are arranged at different heights, so that the height at which the shelf board 91 is arranged can be changed, and the plurality of shelf boards can be arranged at different heights. 91 can be arranged simultaneously at a plurality of heights, and storage efficiency can be further improved.

On the other hand, when the shelf board 91 is not used, the panel container 30 can be used by removing only the shelf board 91 from the shelf board holder 81, and the shelf board holder 81 is attached to the top panel 11 and the bottom panel. By releasing the pressure contact with the panel 16, for example, in this embodiment, by adjusting the screw structure of the holder post 101 and the adjuster 103 to reduce the height, the panel container 30 can be easily removed from the main body of the panel container 30. is. Furthermore, since the two sets of ladder-like structures 109 are separated from each other, the storage space can be reduced.

2. Second Embodiment (a) Configuration of Cart for Transportation Next, the configuration of a car for transportation according to a second embodiment of the present disclosure will be described with reference to FIGS. 8 to 10. FIG. FIG. 8 shows a carriage 10A for transportation according to a second embodiment of the present disclosure, in which a panel container 30A is mounted on the upper side of the carriage body 50, and the front panel 12 of the panel container 30A is opened. is a perspective view. FIG. 9 is a perspective view of the carriage 10A for transportation of the second embodiment. It is a figure in a state where 10A and 10B are a plan view and a front view of part of the side frames of the panel container 30A and the carriage body 50. FIG.

A carriage 10A for transportation of the second embodiment includes a carriage body 50 similar to that of the first embodiment, and a panel container 30A mounted on the top of the carriage body 50. As shown in FIG. As shown in FIG. 9, unlike the panel container 30 of the first embodiment, the panel container 30A can open the top panel 11, the bottom panel 16, and the rear panel 13 in addition to the front panel 12, respectively. Further, as shown in FIG. 8, inside the panel container 30, a shelf board holder 82 extending in the Y direction from the inner surface of the left panel 14 to the inner surface of the right panel 15 and a shelf board holder 82 supported by the shelf board holder 82 are provided. A shelf plate 92 is arranged.

(b) Configuration of panel container In the panel container 30A used in the carriage 10A for transportation of the present embodiment, not only the front panel 12 but also the bottom panel 16, the top panel 11 and the rear panel 13 can be folded. It differs from the panel container 30 in form. Since the front panel 12, the left panel 14 and the right panel 15 are the same as in the first embodiment, other panels will be explained.

(i) Rear Panel As shown in FIG. 9, the rear panel 13 of the panel container 30A includes, in order from the -Y direction side, a third rear partial panel 13c having a relatively narrow width in the Y direction and a third rear partial panel 13c having a relatively narrow width in the Y direction. It comprises a wide second rear section panel 13b and a first rear section panel 13a. Between the third rear partial panel 13c and the second rear partial panel 13b and between the second rear partial panel 13b and the first rear partial panel 13a, a second rear hinge member 23b and a second rear hinge member 23b are provided, respectively. 1 rear hinge member 23a is arranged. With these arrangements, when viewed from the +Z direction, the first rear partial panel 13a rotates counterclockwise relative to the second rear partial panel 13b, and the second rear partial panel 13b rotates relative to the third rear partial panel 13c. They can be rotated counterclockwise and bent. Like the front panel 12, the folded first rear panel 13a and the second rear panel 13b can be stacked on the outside of the left panel 14, that is, on the -Y direction side.

(ii) Top Panel As shown in FIGS. 8 and 9, the top panel 11 includes, in order from the -Y direction, a first top partial panel 11a having a relatively narrow width in the Y direction and a first partial panel 11a having a relatively narrow width in the Y direction. and a relatively wide second top surface partial panel 11b. In addition, the second top surface portion panel 11b has a clock as viewed from the +X direction side with reference to the first top surface hinge member 21a that rotatably couples the first top surface portion panel 11a and the second top surface portion panel 11b. It can be turned around, and as a result, the top panel 11 can be folded close to the folded bottom panel 16 to be described later, as shown in FIG. Since the top panel 11 can be opened and closed in this way, luggage and heat storage materials can be put in and taken out from other than the front. can improve sexuality.

(iii) Bottom Panel As shown in FIG. 9, the bottom panel 16 of the panel container 30A is tilted when viewed from the +X direction with respect to the hinge structure (not shown) that is the joint with the left panel 14. It can be lifted clockwise so that the bottom panel 16 can be folded with the major surface of the bottom panel 16 in contact with the major surface of the left panel 14 . In this way, not only the front panel 12 but also the bottom panel 16, the top panel 11 and the rear panel 13 can be folded. Alternatively, by folding the panel container 30, a space in the middle of the carriage 10A can be secured. As a result, cargo that does not require temperature control can be loaded on the transportation truck 10A, and depending on the structure of the transportation truck 10A, multiple trucks can be nested together to allow the panel container 30A to be attached when not in use. Space saving can be achieved.

(c) Structure of Shelf Board and Shelf Board Holder FIG. 10(a) is a plan view showing part of the side frames of the panel container 30A and the carriage body 50, with the top panel removed. FIG. 10(b) is a front view showing part of the side frames of the panel container 30A and the carriage body 50 with the front panel 12 removed.

As shown in FIGS. 10(a) and 10(b), the shelf board holder 82 includes a pair of holder lateral beams 111 extending in the horizontal direction, that is, the Y direction, a lateral beam connecting bar 112 connecting them in the X direction, and a pair of A fixed plate 114 having a wide planar shape is provided at the tip of the holder horizontal beam 111 of the holder. An adjuster 115 is provided between one end of the retainer lateral beam 111 and the fixing plate 114 . The adjuster 115 has a function of adjusting the width from the fixed plate 114 at one end of the retainer lateral beam 111 to the fixed plate 114 at the other end. By having a structure corresponding to a nut, the widthwise length of the shelf plate holder 82 can be extended or shortened by rotating one relative to the other. By adopting such a structure, even when the width inside the panel container 30 is different, the length of the shelf board holder 82 in the width direction can be arbitrarily adjusted so that the shelf board holder 82 can be attached to the panel container 30. An appropriate compressive load can be applied to the left panel 14 and the right panel 15 so that they can be stably fixed to each other.

The fixing plate 114 is provided to increase the contact area of the portion that contacts the left panel 14 and the right panel 15, similarly to the fixing plate 104 provided at the tip of the holder post 101 of the first embodiment. ing. This is to avoid applying a local concentrated load to the left panel 14 and the right panel 15, and to suppress deformation and damage to the panels. Also, the shape of the fixing plate 114 and the fact that it can be tilted with respect to the axis of the horizontal beam of the holder are the same as those described in the first embodiment.

In addition, a plate-like shelf board 92 is supported above the shelf board holder 82. On the +X direction side and the -X direction side of each of the two holder lateral beams 111 of the shelf board 92, , and width direction guides 113 are provided adjacently. As a result, when the shelf board 92 is about to shift in the X direction, the width direction guide 113 comes into contact with one of the holder horizontal beams 111 of the shelf board holder 82, thereby suppressing the shift, and the shelf board 92 is prevented from shifting. Possibility of carelessly dropping off from the shelf plate holder 82 can be reduced.

In addition, the fixing plate 114, which is the tip of the retainer lateral beam 111 of the shelf plate retainer 82, has the left panel 14 and the right panel 15 directed toward the outside of the panel container 30, that is, the left panel 14 faces the -Y direction. , the load is applied in the direction of pushing out the right panel 15 in the +Y direction. At this time, since the first side frame 51 and the second side frame 52 of the carriage body 50 are adjacent to the -Y direction side of the left panel 14 and the +Y direction side of the right panel 15, respectively, the inside of the panel container 30 It can support the force pushing outward from the Therefore, even when the shelf board holder 82 presses the left panel 14 and the right panel 15 with increasing force, it is possible to prevent the panels from deforming in the direction of expanding outward.

In the carriage 10A for transportation of this embodiment, the top panel 11 can be opened and closed, and it is difficult to press and fix the shelf board holder 81 to the top panel 11 and the bottom panel 16 as in the first embodiment. suitable for when In addition, in this embodiment, by using a shelf plate holder 82 that can be pressed against and fixed to the left panel 14 and the right panel 15, and a shelf plate 92 that can be placed on and supported by the shelf plate holder 82, the first embodiment can be used. Similarly, even if there is no space on the floor surface of the storage space 20 inside the panel container 30 for loading additional cargo, additional cargo can be loaded on the shelf board 92 provided at the middle position in the height direction. . Therefore, the storage efficiency of luggage is improved. Furthermore, it is also possible to open and close the top panel 11 while using the shelf plate 92, which further improves workability.

In addition, in this embodiment, the shelf board holder 82 is pressed against both the left panel 14 and the right panel 15 instead of engaging the shelf board 92 with the side panel by a weak engaging means such as a hook-and-loop fastener. Because it is held by the shelf, heavier loads can be loaded on the shelf. Furthermore, the arrangement position of the shelf board holder 82 in the height direction can be arbitrarily changed, and the plurality of shelf board holders 82 and the corresponding plurality of shelf boards 92 can be arranged at different heights. , storage efficiency can be further improved.

When the shelf plate 92 is not used, the panel container 30 can be used by easily removing the shelf plate holder 82 and the shelf plate 92 . By releasing pressure contact with the left panel 14 and the right panel 15, the shelf board holder 82 is shortened in width by adjusting the screw structure of the holder lateral beam 111 and the adjuster 115 in this embodiment. Therefore, it can be easily removed from the main body of the panel container 30 .

It can be rotated clockwise to open halfway.

The fourth top surface partial panel 11d arranged on the back side has a structure that cannot be opened and closed. However, the fourth top surface partial panel 11d on the far side rotates counterclockwise with respect to the third top surface partial panel 11c about the second top surface hinge member 21b as a rotation axis when viewed from the +Y direction side. It is also possible to have a structure in which the front side or the back side can be opened only halfway. By adopting such a structure, it is possible to put in and take out luggage and heat storage material from other than the front, and the front side of the top panel 11 can be opened together with the front panel 12, so that a wide open area of the storage space can be secured. . Therefore, it is more advantageous to improve the workability in a situation where a sufficient work space cannot be secured around the carriage 10B for transportation.

(c) Structure of Shelf Board and Shelf Board Holder FIG. 12(a) is a plan view showing part of the side frames of the panel container 30B and the carriage body 50 with the top panel removed. FIG. 12(b) is a front view showing part of the side frames of the panel container 30B and the carriage body 50 with the front panel 12 removed.

As shown in FIGS. 12(a) and 12(b), the shelf board holder 83 is hooked along each of the left panel 14 on the -Y direction side and the right panel 15 on the +Y direction side so as to cover the upper ends thereof. is hooked and suspended. The shelf plate holder 83 along the left panel 14 includes a hook-shaped panel fixing hook portion 121 and a film-like or plate-like shelf plate holding sheet 122 connected to the panel fixing hook portion 121. A fixing hook portion 121 is hooked and fixed to the upper end of the left panel 14 , and a shelf board holding sheet 122 is hung along the inner surface of the left panel 14 . The shelf plate holder 83 is also provided on the right panel 15 in a similar configuration.

In this embodiment, the panel fixing hook portion 121 is integrally formed with the same material as the shelf board holding sheet 122 at the tip of the shelf board holding sheet 122 . However, the panel fixing hook portion 121 and the shelf board holding sheet 122 may be made of the same material or may be made of different materials. For example, a metal plate, a resin plate, or a resin film may be used, or a member having a mesh structure made of metal, resin, fiber, or the like may be used. Specifically, when a rigid member is used, rigid resins such as polypropylene, polyethylene terephthalate, acrylonitrile-butadiene-styrene (ABS), polyvinyl chloride, and polycarbonate, which have high bending strength and durability, Examples include fiber-reinforced resins and rust-resistant metals such as aluminum, aluminum alloys, and stainless steel. In the case of a sheet-like or film-like member, polypropylene, polyethylene terephthalate, acrylonitrile-butadiene-styrene (ABS), polyvinyl chloride, polycarbonate, triacetylcellulose (TAC), polyimide and the like can be used.

Further, the shelf plate holding sheet 122 is provided with a plurality of position adjustment slits 123 so that the height of the shelf plate 93 can be changed as appropriate. By hooking the sheet hooks 124 attached to the tip of the shelf board 93 via the connecting sheets 125 which are flexible members connected to both ends of the shelf board 93 to the position adjustment slits 123, the shelf board 93 is held at a fixed position. can be fixed to

When the shelf plate 93 is a rigid plate, the angle of the sheet hook 124 is finely adjusted, and considering the workability of properly hooking it to the position adjustment slit 123 of the shelf plate holding sheet 122, the shelf plate 93 and the sheet hook It is preferable that the connecting sheet 125 connecting with 124 is made of a resin base material or the like having a certain degree of flexibility. However, such a connecting sheet 125 is not an essential component of the present embodiment. Alternatively, a structure in which the shelf plate 93 and the shelf plate holding sheet 122 are directly engaged by screws, rivets, or any other joining means may be used. Further, the position adjusting slit 123 may not be formed in the shelf board holding sheet 122. For example, the two sets of shelf board holding members 83 may be connected to each other by a flexible member such as a film. Alternatively, a shelf board may be mounted on this member.

Since the left panel 14, the right panel 15, and the top panel 11 contain heat insulating material inside, as described above, the panel fixing hook portion 121 of the shelf plate holder 83 is sandwiched between these contact portions. However, if it is within the elastic deformation range of the panel, the shape of the panel follows the sandwiched member, so that the airtightness of the panel container 30B is less likely to be impaired. In addition, since the holding effect of the shelf plate holder 83 is enhanced by sandwiching the panel fixing hook portion 121 between the adjacent panels in this way, the panel fixing hook portion 121 can be set to the extent that the airtightness of the panel container 30B is not impaired. It is preferred that the portion 121 be in a state of receiving a pinching force from adjacent panels.

In this embodiment, the shelf board holder 83 is hooked to the upper ends of the left panel 14 and the right panel 15 by hooks. The portion may be fixed to the panel with an adhesive or the like, or may be engaged with the panel by a detachable engagement method such as a hook-and-loop fastener depending on the load capacity of the luggage.

The trolley for transportation 10B of this embodiment is also suitable for the case where the top panel 11 can be opened and closed, and two sets can be assembled by hooking hook structures on the upper ends of the left panel 14 and the right panel 15 that are arranged to face each other. , and the shelf board 93 is placed on the shelf board holders 83 and supported. By adopting such a configuration, it is possible to use the end portion of the panel, which is less likely to be equipped with a vacuum heat insulating material and is relatively strong in terms of strength, to store the shelves 93 and cargo. load, reducing the risk of panel deformation and damage. Further, since the shelf plate holder 83 is simply hooked on the upper end of the panel and fixed by its own weight, it is extremely easy to attach and detach, improving workability. Furthermore, since the shelf plate holder 83 and the shelf plate 93 are suspended from the panel, even if the panel container 30B is subjected to external vibration or impact, the shelf plate holder 83 itself will move in the opposite direction. Vibration is expected to have the effect of alleviating the transmission of these external vibrations and impacts to the cargo.

4. Fourth Embodiment (a) Configuration of Transportation Cart Next, the configuration of a transportation trolley according to a fourth embodiment of the present disclosure will be described with reference to FIGS. 13 and 14. FIG. FIG. 13 is a perspective view showing a transportation trolley 10C according to the fourth embodiment of the present disclosure, in which a panel container 30C is mounted on the upper side of the trolley body 50. FIG. FIG. 14 is a perspective view showing the shelf holder 84 arranged inside the panel container 30C.

A carriage 10C for transportation according to the fourth embodiment includes a carriage body 50 similar to those of the first, second, and third embodiments, and a panel container 30C mounted on the top of the carriage body 50. FIG. As shown in FIGS. 13 and 14, the panel container 30C internally supports a shelf plate holder 84 having a rack structure configured in a substantially rectangular parallelepiped shape by combining a plurality of cylindrical members. The shelf board holder 84 has two vertically extending holder columns 131 horizontally connected to each other by holder horizontal beams 132 at the upper and lower ends thereof, and a plurality of horizontal beams 133 at the intermediate portion in the height direction. and the two sets of ladder-like structures 134 are connected horizontally by retainer cross beams 132 at their upper and lower ends. It has a rack structure. The horizontal beams 133 have a function of horizontally connecting the support columns 131 and a function of supporting the shelf board 94 .

The shelf plate holder 84 is only mounted on the inner surface of the bottom panel 16 of the panel container 30C, and no load is applied to panels other than the bottom panel 16. - 特許庁In addition, since the shelf board holder 84 is in contact with the bottom panel 16 with a wide contact area by means of the four holder lateral beams 132, which are a plurality of cylindrical members, the load on the bottom panel 16 is reduced. The risk of deformation or damage to the bottom panel 16 is reduced.

(b) Configuration of Panel Container The panel container 30C used in the carriage 10C for transportation of this embodiment has the same structure as the panel container 30B described in the third embodiment except for the shelf plate holder 84 and the shelf plate 94. Therefore, the description is omitted.

(c) Structure of Shelf Board and Shelf Board Holder FIG. 14 is a perspective view of the shelf board holder 84 for explaining the structure of the shelf board holder 84 and the shelf board 94 arranged inside the panel container 30C. . The shelf plate holder 84 has four vertical holder supports 131 and eight horizontal holder beams 132 arranged at the upper and lower ends of the horizontal members connecting the four, thereby forming a substantially rectangular parallelepiped. Further, a predetermined number of horizontal beams 133 are arranged along two opposing side surfaces.

The shelf board 94 is a plate-like member, and the shelf board 94 is supported by the shelf board holders 84 by bringing both ends of the shelf board 94 into contact so as to straddle the two facing horizontal beams 133, and the panel It will be fixed to the container 30C. An arbitrary number of shelf boards 94 can be arranged at arbitrary positions of the horizontal rails 133 formed in a plurality of stages, and unnecessary shelf boards can be removed in advance. Although the shelf board 94 is simply mounted on the two horizontal beams 133, the shelf board hooks 105 of the shelf board 91 in the first embodiment and the width direction guides 113 of the shelf board 92 in the second embodiment are mounted. Thus, the shelf 94 may have a structure to prevent the shelf 94 from slipping or falling off from the shelf holder 84 .

The holder struts 131, the horizontal holder beams 132, and the horizontal beams 133, which constitute the shelf plate holder 84, are cylindrical members having a circular cross-section, but they are not limited to this, and may have a square cross-section. , a rectangular prism member, a combination of angle members having an L-shaped cross section, a hollow round pipe or square pipe, or a combination of these.

In addition, although the shelf board holder 84 has a structure that cannot be disassembled, the structure may be such that part or all of the holder strut 131, the holder horizontal beam 132, and the horizontal beam 133 can be individually disassembled, and can be folded. structure. Even if the shelf board holder 84 has a structure that cannot be disassembled, the space of the panel container 30C and the transportation cart 10C can be occupied by taking out the shelf board holder 84 from the panel container 30C when not in use. However, if the shelf holder 84 is disassembleable or foldable, the shelf holder 84 itself can be compactly stored when not in use.

In the carriage 10C for transportation of the present embodiment, the shelf plate holder 84 having the rack structure can be arranged inside the panel container 30C as it is, and the shelf plate 94 can be fixed inside the panel container 30C very easily. can be done. Structurally, the rack structure is very stable, and there is little danger that the shelf plate holders 84 will be deformed or damaged by the load. In addition, the shelf board holder 84 is fixed to the panel container 30C only by mounting the shelf board holder 84 above the bottom panel 16, and the shelf board holder 84 and the bottom panel 16 are separated by 4 Since the book holder lateral beam 132 has a large contact area, the shelf board holder 84 can be stably fixed, and the risk of deformation and damage to the bottom panel 16 can be reduced.

5. Modifications Various modifications and changes are possible without being limited to the above-described embodiments, and they are also within the scope of the present disclosure. Some modifications are given below.

(a) Modification 1
FIG. 15 is a diagram showing shelf plates 91A, 91B and 91C that are Modification 1 of the first embodiment, showing the same arrangement as in FIG. It is an enlarged view. The structure of the shelf board when the shelf board is mounted on and fixed to the horizontal beam 102 of the shelf board holder 81 can take various configurations other than the structure described in the first embodiment. For example, the shelf board 91A shown in FIG. 15A has a shelf board hook 106 perpendicular to the main surface of the shelf board 91A attached to the tip of the -Y direction side. It is arranged inside the panel container, that is, on the +Y direction side of the horizontal beam 102 . This means that the shelf board hooks 106 of the shelf board 91A are arranged in such a direction as to push out the horizontal beams 102 at both ends toward the left panel 14 and the right panel 15 from the shelf board 91A side.

The shelf board 91B shown in FIG. 15(b) has a shelf board hook 107 perpendicular to the main surface of the shelf board 91B at the tip on the -Y direction side. When the shelf board holder 81 tries to shift away from the shelf board 91B, or when the shelf board holder 81 tries to shift in the direction of approaching the shelf board 91B. also has the effect of suppressing the progress of deviation.

On the other hand, the shelf board 91C shown in FIG. 15(c) does not have a shelf board hook perpendicular to the main surface of the shelf board 91C. By having the concave portion including the circular arc of the diameter, displacement of the shelf plate 91C is suppressed. In such a structure, it is not necessary to attach another member such as a hook to the shelf board main body, and the structure can be simplified.

(b) Modification 2
Next, the configuration of Modified Example 2 of the carriage for transportation of the present disclosure will be described with reference to FIGS. 16 and 17. FIG. FIG. 16 is a perspective view showing a carriage 10D for transportation according to Modification 2. As shown in FIG. 17A and 17B are a side view and a front view showing the arrangement of the shelf plate holders 85 inside the panel container 30D. FIG. 17A is a cross-sectional view of the panel container 30D cut along a plane perpendicular to the Y-axis near the center in the Y-direction, viewed from the +Y-direction side. FIG. 17(b) is a front view of the panel container 30D viewed from the +X direction side with the front panel 12 removed.

As shown in FIGS. 17(a) and 17(b), the shelf plate holder 85 has two sets of identical ladder-like structures 138 on the inner surface of the left panel 14 and the inner surface of the right panel 15, respectively. It is joined and fixed in contact with the bottom panel 16 . These two sets of ladder-like structures 138 can also be referred to as the first shelf retainer and the second shelf retainer, respectively. In the first embodiment, the shelf plate holder is in pressure contact with the top panel 11 and the bottom panel 16, but in this modification, the ladder-like structure 138 is mounted on the bottom panel 16 by its own weight. It does not abut on the top panel 11, but instead joins the left panel 14 or the right panel 15. As shown in FIG.

Each ladder-like structure 138 that constitutes the shelf plate holder 85 includes a pair of holder posts 135 extending in the vertical direction, and horizontally connecting the holder posts 135 to each other and holding the shelf plate 91. and a plurality of rungs 136 having roles. In this modified example, the holder struts 135 and the horizontal beams 136 have a structure in which square bars having a rectangular cross-sectional shape are combined, but the cross-sectional shape and the like are not limited to this. However, when rectangular or square cross-sectional shapes are combined, compared to the case of using a cylindrical material, the contact area between the retainer strut 135 or the horizontal beam 136 and the left panel 14 or right panel 15, Since the contact area between the horizontal beam 136 and the bottom panel 16 can be increased, this is advantageous from the viewpoint of reducing the load on the panel.

The shelf plate holder 85, the left panel 14 and the right panel 15 are joined to each other via joining means 137, and any joining method such as an adhesive can be applied as the joining means 137. FIG. In this case, most of the load of the shelf board holder 85, the shelf board 91, and the loads mounted on the shelf board 91 is supported by the bottom panel 16, but partly by the left panel 14 and the right panel 15. is also dispersed. However, the contact area between the ladder-like structure 138 and the left panel 14 and right panel 15 is large, and the risk of deforming or damaging the left panel 14 and right panel 15 is very small. In addition, the load on the bottom panel 16 is also dispersed due to the wide contact area of the horizontal beams 136, and the risk of deformation and damage to the bottom panel 16 can be similarly reduced.

(c) Modification 3
The configuration of Modified Example 3 of the carriage for transportation of the present disclosure will be described with reference to FIGS. 18 and 19. FIG. FIG. 18 is a perspective view showing a carriage 10E for transportation according to Modification 3. As shown in FIG. 19A and 19B are a side view, a plan view and a front view showing the structure and arrangement of the shelf holder 86 inside the panel container 30E. FIG. 19(a) is a side view of the shelf board holder 86 in a no-load state. FIG. 19(b) is a plan view of the panel container 30E and part of the side frames of the carriage body 50 with the top panel removed. FIG. 19C is a front view of part of the side frame of the panel container 30E and the carriage body 50 with the front panel 12 removed.

As shown in FIG. 18, the carriage 10E for transportation of Modification 3 has a Y-direction from the inner surface of the left panel 14 to the inner surface of the right panel 15 inside the panel container 30E, as in the second embodiment. A shelf retainer 86 is disposed extending to the . However, the shelf plate holder 86 of Modified Example 3 does not have the horizontal beams of the holders or the horizontal beam connecting bars for connecting the horizontal beams of the holders, and as shown in FIG. The holder 86 itself has a structure in which the axis of the main surface is curved in an unloaded state.

That is, the shelf plate holder 86 itself has a shape of a shelf plate, and includes a plate spring-like elastic plate member 141 that is deformed by a predetermined load. In addition, the shelf plate holder 86 is provided with side fixing members 142 having surfaces perpendicular to the main surface at both ends thereof. As a result, the shelf board holder 86 is curved in an unloaded state, making it difficult to fix it in the panel container 30E. When some cargo is loaded on the shelf plate holder 86, the curved state is eliminated, the internal stress generated in the elastic plate member 141 and the load of the loaded cargo are balanced, and the side surfaces, which are both ends of the shelf plate holder 86, are balanced. Fixtures 142 are pressed against the inner surfaces of left panel 14 and right panel 15, respectively. As a result, the shelf plate holder 86 on which cargo is mounted can be fixed at any position other than the bottom surface of the storage space inside the panel container 30E.

As described above, in this modified example, by using the elastic plate member 141 which is composed of an elastic member such as a leaf spring structure that is curved when no load is applied and deforms into a flat state when a load is applied, the elastic plate member 141 can be easily bent. , the shelf board holder 86 functioning as a shelf board can be fixed at an arbitrary height within the panel container 30E.

(d) Modification 4
A configuration of a carriage for transportation according to Modification 4 of the present disclosure will be described with reference to FIGS. 20 and 21. FIG. FIG. 21 is a perspective view showing a carriage 10F for transportation according to Modification 4. As shown in FIG. 21A and 21B are a plan view and a front view of part of the side frame of the panel container 30F and the carriage body 50. FIG.

This modification is similar to the carriage 10B for transportation of the third embodiment, but unlike the shelf board holder 83 of the third embodiment, the shelf board holder 83A is provided at the upper end of the left panel 14 and the right panel 15. It is fixed by hooking on the first side frame 51 and the second side frame 52 of the bogie body 50 arranged outside the bogie body 50 instead of hanging it by hooking. Specifically, the upper end of the shelf plate holding sheet 152 hung along the left panel 14 and the right panel is directly hooked to the first side frame 51 and the second side frame 52 of the carriage body 50 and fixed. A side frame fixing hook portion 151 having a is attached. By hooking this on the pillars 55 or the like at the upper ends of the first side frame 51 and the second side frame 52, the shelf board holder 83A is fixed to the panel container 30F. Note that the side frame fixing hook portion 151 may be fixed to any part of the bogie main body 50 as long as it is fixed to the member of the carriage body 50. Other than the support 55, it may be fixed to the horizontal beam 56, or fixed to the support 55 or the horizontal beam. It may be fixed to the connecting member 53 via 56 .

Other configurations of the position adjustment slit 153, the connection sheet 155, the sheet hook 154, etc. are the same as the configurations of the position adjustment slit 123, the connection sheet 125, the sheet hook 124, etc. of the shelf board holder 83 of the third embodiment. is. The same applies to the material of the shelf plate holding sheet 152 and the side frame fixing hook portion 151 . As with the shelf board holders 83 of the third embodiment, these paired shelf board holders 83A can also be referred to as a first shelf board holder and a second shelf board holder, respectively.

The trolley for transportation 10F of this modified example hooks the hook structure to the first side frame 51 and the second side frame 52 of the trolley body 50 instead of the upper ends of the left panel 14 and the right panel 15, thereby forming two sets of hook structures. Each of the shelf plate holders 83A is suspended, and the shelf plate 93 is fixed thereto. For this reason, if there is no problem with the load resistance and rigidity of the shelf plate holder 83A and the shelf plate 93, even if a heavy load is mounted on the shelf plate 93, almost no load is applied to each panel of the panel container 30F. The risk of deformation and damage to the panel can be significantly reduced. Therefore, it is not necessary to design the strength of the panel container 30F in consideration of the shelf plate holder, the shelf plate, and the load of the cargo on the shelf plate. It is possible to expand the degree of freedom in the design of the panel container, such as making it thinner. Further, since the carriage main body 50 and the panel container 30F are moved and stored as an integral transportation carriage 10F, the relative positions of the shelf board holders 83A and the shelf boards 93 with respect to the panel container 30F may change during movement or storage. There is no possibility of change.

(e) Modification 5
Next, the configuration of the carriage for transportation according to Modification 5 of the present disclosure will be described with reference to FIGS. 22 and 23. FIG. FIG. 22 is a perspective view showing a carriage 10G for transportation according to Modification 5. As shown in FIG. 23A and 23B are a plan view and a front view of the panel container 30G and part of the side frames of the carriage body 50. FIG.

This modification is similar to the transportation cart 10F of Modification 4 described above, but the shelf board holder 83B is different from the shelf board holder 83A of Modification 4. A side frame fixing string member 161, which is a string-like member, is hooked or tied to a side frame pin 166 installed near the upper end of the second side frame 52, and connected to the side frame fixing string member 161. A shelf board holding sheet 162 is suspended and fixed along the left panel 14 and the right panel 15 . As the cord-like member, a tarpaulin member, a textile member such as cotton or chemical fiber, etc., can be cited as a member having high flexibility and low tensile elongation. Examples include, but are not limited to, resin wires such as resin.

Other configurations of the position adjustment slit 163, the connection sheet 165, the sheet hook 164, etc. are the same as the configurations of the position adjustment slit 123, the connection sheet 125, the sheet hook 124, etc. of the shelf board holder 83 of the third embodiment. is. The same applies to the material of the shelf plate holding sheet 162 and the like. As with the shelf board holder 83A of Modification 4, these paired shelf board holders 83B can also be referred to as a first shelf board holder and a second shelf board holder, respectively.

In the carriage 10G for transportation of this modified example, the attachment portion of the shelf board holder 83B to the carriage main body 50 is not a hook structure but a string-like member, so that the structure of the shelf board holder 83B is simplified and the carriage It has the advantage that there are many options for the attachment point to the main body 50 and the attachment method. In this modification, side frame pins 166 are installed near the upper ends of the first side frame 51 and the second side frame 52, and the side frame fixing string members 161, which are the string-like members of the shelf plate holders 83B, are attached to the pins. Although the hooking mode is employed, it is also possible to hook by using some kind of protrusion of the side frame or the like without providing the side frame pin 166 . Moreover, even if such a protrusion does not exist, the string-like member of the shelf plate holder 83B may be directly tied to the support 55 or the horizontal beam 56 to be fixed.

(f) Modification 6
Next, the configuration of the carriage for transportation according to Modification 6 of the present disclosure will be described with reference to FIGS. 24 and 25. FIG. FIG. 24 is a perspective view showing a carriage 10H for transportation according to Modification 6. As shown in FIG. FIG. 25 is a perspective view for explaining the shelf holder 84A arranged inside the panel container 30H.

In the carriage 10C for transportation according to the fourth embodiment, a shelf plate holder 84 having a rack structure configured in a substantially rectangular parallelepiped shape by combining a plurality of cylindrical members is supported inside the panel container 30C. On the other hand, as shown in FIGS. 24 and 25, a carriage 10H for transportation according to the present modification includes a pair of side plates 171 whose main surfaces extend in the vertical direction, and a pair of side plates 171 that extend in the vertical direction. A plurality of shelf plates 94A, 94B, 94C and 94D at a plurality of heights are provided inside a frame-like structure composed of a plate-like member having a top plate 172 and a bottom plate 173 that horizontally connect the upper and lower ends. is provided with a shelf plate holder 84A having a rack structure that can be attached and detached at the same time.

On the inner surface of the pair of side plates 171 of the shelf plate holder 84A, that is, on the surface of one side plate facing the other side, a shelf plate support portion 174, which is a projection for supporting the shelf plate, is provided on the side of the side plate. A plurality of them are arranged along the height direction of the face plate 171 . By sliding and inserting the shelf boards 94A, 94B, 94C, and 94D onto the shelf board supporting portions 174 corresponding to the predetermined heights, a plurality of shelf boards are arranged inside the shelf board holder 84A. can be made In addition, when it is desired to reduce the number of shelves, or when it is desired to place tall items on the shelves, unnecessary shelves can be removed and used as necessary.

In the carriage 10H for transportation of this modified example, a pair of side surfaces, an upper end surface, and a lower end surface of a shelf plate holder 84A having a rack structure are formed of plate-shaped structures such as a side plate 171, a top plate 172, and a bottom plate 173, respectively. , the load resistance is good when a load is loaded, and it is possible to stably load a heavy load. Further, the shelf board holder 84A is fixed to the panel container 30H by simply mounting the shelf board holder 84A above the bottom panel 16, and the shelf board holder 84A and the bottom panel 16 Since the entire surface plate 173 contacts and has an extremely wide contact area, the shelf plate holder 84A can be stably fixed, and the risk of deformation and damage to the bottom panel 16 can be further reduced.

(g) Modification 7
Next, the configuration of the carriage for transportation according to Modification 7 of the present disclosure will be described with reference to FIGS. 26 and 27. FIG. FIG. 26 is a perspective view showing a carriage 10I for transportation according to Modification 7. As shown in FIG. FIG. 27 is a perspective view for explaining the shelf board holder 84B arranged inside the panel container 30I.

This modification is also partially similar to modification 6, but as shown in FIGS. 181, a top plate 182 that horizontally connects the upper ends of the pair of side plates 181, and a connector 183 that rotatably connects the pair of side plates 181 and the top plate 182. A plate holder 84B is provided.

The shelf plate holder 84B is in a state in which the pair of side plates 181 are opened, that is, the pair of side plates 181 are in a state in which the main surfaces of the pair of side plates 181 are substantially perpendicular to the top plate 182 as shown in FIG. 27(a). In this case, just by mounting this on the bottom panel 16 inside the panel container 30I, the top plate 182 is regarded as an intermediate shelf of the shelf plate holder 84B, and the bottom side of the top plate 182, that is, the bottom A load can be mounted separately on the panel 16 and on the top plate 182 respectively. When the shelf board holder 84B is not used, the shelf board holder 84B may be taken out of the panel container 30I as it is. However, as shown in FIG. By folding via 183, the pair of side plates 181 can be folded into a plate so that the main surfaces of the pair of side plates 181 and the top plate 182 are substantially parallel to each other, that is, can be folded into a single plate for compact storage. can.

The shelf plate holder 84B of the trolley for transportation 10I of this modified example has a simple structure, is easy to assemble and fold, and can be flatly and compactly stored when folded.
